• Abstract:
  This research studies the effectiveness of a dynamic message sign (DMS) using a driving ; simulator. Over 100 subjects from different socio-economic and age groups were recruited to ; drive the simulator under different traffic and driving conditions and various travel-related ; DMS messages. The subjects drove between a specified pair of origin and destination while ; choosing their own route in a fairly realistic 12 × 12 mi2 (20 × 20 km2) network that included ; road signs, traffic signals, three-dimensional buildings and trees, and other roadside objects. ; Their driving behavior, including changes in driving speed, route choice and diversion, and ; travel time perception in the presence of DMS were studied. In addition to the driving simulator ; experiment, a stated preference analysis was conducted through three sequential survey ; questionnaires. The questionnaire data was utilized to better understand drivers’ perceptions of ; the efficiency-related attributes. The study concluded that DMS is a safe device, since drivers ; did not reduce their speed significantly to read the DMS contents. Furthermore, quantitative ; information provided by DMS affected drivers’ route choice significantly and drivers were ; quite sensitive to travel time change. However, the diversion rate due to a second DMS with ; qualitative information was much less than what the subjects stated in the survey.
